As the demand for data has grown with the advent of 4G networks and smartphones we’ve seen the major carriers switch their plans. Once, they offered unlimited data alongside tiered monthly tariffs for call minutes and texts, now they have reversed the equation. New plans from Verizon and AT&T this summer offer unlimited minutes and texts, but charge for data usage. Take a look at AT&T Mobile Share vs. Verizon Share Everything to see how they stack up.

T-Mobile has decided to buck the trend and offer “Unlimited Nationwide 4G Data” on its HSPA+ network as an add-on for all of its voice and text plans. This is completely uncapped and throttle-free data. Add it to a Value plan which isn’t tied to a subsidized device and it will cost you an extra $20 per month. Add it to a Classic plan and you’re looking at $30 per month extra. That shakes out at $70 per month for unlimited talk, text, and data on the Value plan, and $90 for the same on a Classic plan.

T-Mobile’s new plans will be available starting on Sept. 5 and many consumers are liable to be tempted by what look like straightforward plans at reasonable prices — a far cry from the complicated new plans from AT&T and Verizon.

The only downside is that you can’t take an unlimited data plan and use your hotspot capability to tether other devices to your smartphone. If you want to use your phone as a hotspot, you’ll have to stick with one of the limited plans which throttles once you reach your monthly limit.

According to The Verge, T-Mobile would not confirm whether the plans would still be available when 4G LTE rolls out.

New and existing customers can sign up for the new plans at T-Mobile stores or online Sept. 5.
